SPECIFICATION formingpart of Letters Patent No. 737,112, dated August 25, 1903. Application filed January 9. 1903. Serial No. 138,404. (No model.)

v .To all whom it may concern;-

Be it known that LSAMUEL JONES, a citihave invented certainnew and useful Improvementsin Plane-Bits, of which the following is a specification.

Planes designed for carpenters and joiners use have the bit for the most part reinforced and strengthenedby a cap or stay plate,

held thereto by a clamp bolt or-screw. When sharpening the bit either by'grinding or wh etting, it becomes necessary toreimove the cap or stay plate, so that the face of the bit may be presented to the grindstoneor oil-stone to enable the removal of the wire-edge and the securance of a keen cutting. edge. The removal and the proper replacement ofv the cap-plate are almost always attended with vexation for one reason or another, which it is the purpose of the present invention to over- This invention, enables the proper sharpening of the bit without necessitating the removal of the cap-plate, which is composed of sections hingedly connected, the lower section being free to beturned back upon the bit out of the way and the upper section being secured to the bit in the usual manner to admit of adjustment of the cap or stay plate as the bit wears away. I

The invention consists of a planebit having a cap or stay plate hinged thereto,* so as to be thrown back out of the way. to admit of proper sharpening of the bit.

The invention also consists of a cap or stay plate for plane-bits composed of hinged sections. 7

The invention further consists ofithenovel features, which hereinafter will be more fully to in the following description and indicated in all the views of the drawings by the same reference characters.

The plane-bit 1 may be of any pattern or make adaptedTfor the stock of a carpenters or joiners plane and is provided with the cap or stay plate 2, secured thereto by the bolt or clamp screw 3. The cap or stayplate is composed of sections 4 and 5, hinged together in any way to admit of the lower section 4. folding back upon the bit' out of the way. The stay portion 4 is hinged to the bit 1 through the part 5 and can be turned-instantly to occupy either an operative position or be out of the way. The part 5 can be adjusted to admit of shifting the'cap or stay plate to compensate for wear of the bit. After the bit has been removed from the plane-stock (not shown) it may be sharpened in the accustomed way by folding the stay-section 4. upon the bit, as shown in Fig.12; it not being necessary to remove the cap'or to loosen the clamp-screw. After the bit has been sharpened the section 4.- is turned into a normal position and the bit replaced in the stock in 2. 'A cap-plate-or stay for a plane-bit composed of hinged sections, substantially as specified. v

3. In combination with a plane-bit, a stay,

, an attaching-section having the stay hinged thereto, and means for adjustably connecting the attaching-section to the said bit, substantiallyas set forth.

4. In combination with a plane-bit, a cap.

plate composed of hinged sections, and means for adj ustably connecting the upper section with thebit, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses. A
